The practice of adaptation throws open a vast area of activity, which stretches from the orchestration of simple folk melodies to the arrangement of canonical works to the enhancement or defamiliarization of original material. Arnold Schönberg showed his ability in this area by also adapting Viennese ballads. Several decades later, Bernd Alois Zimmermann saw arranging as a natural part of a composer’s craft. Within this framework, and especially beyond it, well-known music can open up spaces never heard before.
